Description

Technical Field

[0001] The utility model relates to the technical field of glue coating equipment, and particularly relates to a glue coating mechanism. Background Technique

[0002] With the national planning and support for the development of the new energy vehicle industry, the market ownership of new energy vehicles has been continuously increasing, and pure electric or hybrid vehicles are becoming more and more popular in people's lives. Among them, the battery pack, as the core component of an electric vehicle, is mainly used to provide power for the new energy vehicle to continue driving. At the same time, the safety and structural strength of the battery pack have attracted more and more attention, and the improvement of the battery pack safety has always been the focus of the industry's attention.

[0003] Since the battery pack is provided with multiple battery modules for outputting electric energy outside the battery pack, as well as various electrical components, the sealing performance of the battery pack is particularly important for the overall installation of the battery pack. Generally speaking, each plate member constituting the battery pack housing or components such as a cold plate and a bottom guard plate assembled on the battery pack housing are connected to each other through connecting members such as rivets and flow drill screws, and via riveting or flow drill screw tightening (FDS) processes. During the driving process of the vehicle, the connecting members on the battery pack housing are prone to loosen due to bumps and vibrations, resulting in a decrease in the airtightness of the battery pack.

[0004] In order to avoid the decrease in the airtightness of the battery pack and affect the use safety of the battery pack, currently, a method of coating a sealing glue on the above-mentioned connecting members is adopted to improve the airtightness between the battery pack housing and the connecting members. However, in the prior art, the glue coating on the connecting members is usually that an operator holds a container filled with sealing glue and manually extrudes the glue to achieve the coating of the sealing glue. During this process, the amount of glue discharged is only manually controlled by the operator according to experience, and the amount of glue consumed for each glue coating is not fixed. When the amount of glue coating is too much, it will cause waste of glue and increase the production cost, while when the amount of glue coating is too little, the glue coating effect is poor, and it is difficult to ensure the sealing performance at the connecting member. Therefore, the existing glue coating method has problems of inconsistent glue coating amount and poor glue coating effect. Summary of the Utility Model

[0005] In view of this, the utility model aims to propose a glue coating mechanism that can quantitatively coat glue and improve the glue coating effect.

[0006] To achieve the above object, the technical solution of the utility model is realized as follows:

[0007] A glue application mechanism includes a cylinder body, and a channel for outputting glue is provided inside the cylinder body; a truncation mechanism is arranged inside the cylinder body adjacent to the outlet of the channel. The truncation mechanism includes a slider slidably and sealingly installed inside the cylinder body, and a reset mechanism for driving the slider to reset; when the slider is driven to approach the channel, the channel is closed by the slider to truncate the glue in the channel.

[0008] Further, the truncation mechanism further includes a push rod arranged along the axial direction of the cylinder body, and one end of the push rod has an inclined contact surface; when the push rod is driven to move downward to drive the contact surface to push against the slider, the slider approaches and separates the channel.

[0009] Further, an installation groove is formed by the inner wall of the channel extending radially outward, and the slider is slidably and sealingly embedded in the installation groove;

[0010] A chute communicating with the installation groove is provided inside the cylinder body, and the push rod is slidably arranged in the chute.

[0011] Further, guiding ribs are provided in the installation groove, and the guiding ribs can be embedded in the grooves on the slider.

[0012] Further, there are two guiding ribs provided on two opposite sides of the inner wall of the installation groove.

[0013] Further, the reset mechanism is arranged between the slider and the installation groove; the reset mechanism can drive the slider away from the channel to conduct the channel.

[0014] Further, the reset mechanism includes an elastic member, and the elastic member abuts between the slider and a blocking portion on the inner wall of the installation groove; when the slider is driven to approach the channel, the elastic member is compressed to store energy.

[0015] Further, the elastic member is a spring.

[0016] Further, the truncation mechanism is configured to be two arranged on two opposite sides of the channel; the two truncation mechanisms are arranged oppositely, and the two sliders can approach and abut against each other to truncate the channel.

[0017] Further, a sealing ring surrounding the channel is provided on the lower end surface of the cylinder body.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] The glue application mechanism of the present utility model drives the slider of the truncation mechanism to move during the glue application process by setting a cylinder body and a truncation mechanism, so that the slider truncates the glue in the channel of the cylinder body, enabling a certain amount of glue to be extruded by the slider and coated on the connecting piece, maintaining the consistency of the glue application amount each time, avoiding waste of glue, thereby realizing quantitative glue application and improving the glue coating effect.

[0020] The truncation mechanism includes a push rod arranged in the cylinder body. One end of the push rod is provided with an inclined contact surface. When the contact surface pushes against the slider to move, the slider can approach and separate the channel. Generally, the glue application mechanism is connected to an external driving mechanism, so that the driving mechanism can drive the slider to move through the push rod, thereby truncating the glue in the channel and realizing quantitative glue application.

[0021] The slider is embedded in the installation groove communicating with the channel of the cylinder body, and the push rod is slidably arranged in the chute. Through the setting that the chute is connected to the installation groove, the push rod can be integrated inside the cylinder body, thereby improving the structural compactness of the cylinder body.

[0022] The installation groove is provided with guiding ribs, which can be embedded in the grooves on the slider. Through the setting of the guiding ribs, it can play a guiding role in the movement of the slider and can also provide additional support for the slider to reduce the generation of play between the slider and the installation groove, thereby improving the smoothness of the slider movement.

[0023] There are two guiding ribs located on two opposite sides of the inner wall of the installation groove, which can better support the two opposite sides of the slider and further improve the smoothness of the slider movement.

[0024] The reset mechanism is arranged between the slider and the installation groove, and the reset mechanism can drive the slider away from the channel to conduct the channel.

[0025] The reset mechanism includes an elastic member, and the elastic member abuts between the slider and the blocking portion on the inner wall of the installation groove. When the slider is driven to approach the channel, the elastic member is compressed and stores energy. Using the elastic member as the reset mechanism, it has good durability and has a large thrust when the elastic member releases energy to ensure the effective reset of the slider, thereby improving the reliability of the reset mechanism.

[0026] The elastic member is a spring. The spring has a small volume and a large compression stroke, enabling the spring to push the slider to move a sufficient distance to ensure the reset of the slider.

[0027] The truncating mechanism is configured to be two, which are arranged on two opposite sides of the channel, and the two truncating mechanisms are arranged oppositely. The two sliders can approach and abut against each other to truncate the channel. By arranging two oppositely arranged truncating structures, the sliders of the two truncating structures move together to truncate the glue in the channel, thereby reducing the moving stroke of each slider, which is beneficial to the realization of the glue application operation of this glue application mechanism.

[0028] A sealing ring surrounding the channel is provided on the lower end surface of the cylinder body. By providing the sealing ring, the sealing performance between the cylinder body and the battery pack housing is improved, preventing the glue from overflowing outside the cylinder body, thereby enhancing the glue application effect on the connecting piece and improving the sealing performance of the battery pack.

[0041] In addition, in the description of the present utility model, unless otherwise clearly defined, the terms "installation", "connection", "connection", "connector" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood in combination with specific situations.

[0042] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0043] This embodiment relates to a glue application mechanism for coating a sealing glue on the battery pack housing 9. In terms of the overall structure, as Figure 1 、 Figure 2 and Figure 3 shown, the glue application mechanism of this embodiment includes a cylinder body 1 and a truncation mechanism.

[0044] Among them, a channel 101 for outputting glue 3 is provided inside the cylinder body 1. The truncation mechanism is arranged inside the cylinder body 1 adjacent to the outlet of the channel 101. The truncation mechanism includes a slider 2 slidably sealed and installed inside the cylinder body 1, and a reset mechanism for driving the slider 2 to reset. When the slider 2 can be driven to approach the channel 101, the channel 101 is closed by the slider 2 to truncate the glue 3 in the channel 101. And in specific implementation, the slider 2 divides the channel 101 into upper and lower parts.

[0045] During the glue application process, the channel 101 is filled with glue 3. The bottom end of the cylinder body 1 of the glue application mechanism of this embodiment is abutted against the battery pack housing 9, and the connector 10 to be coated with glue 3 is covered. At this time, the truncation mechanism is driven to make the slider 2 truncate the glue 3, and the glue 3 below the slider 2 is coated on the connector 10. And it can be understood that since the slider 2 truncates the glue 3, when the slider 2 moves, the glue 3 in the lower part of the channel 101 is squeezed downward by the slider 2, so that the glue 3 is applied with a certain pressure and is tightly coated on the connector 10, having a good glue application effect. At the same time, the amount of glue applied is no longer affected by the skills of the operator, and the working efficiency of the glue application work can be improved.

[0046] At the same time, the slider 2 moves and the amount of glue 3 pushed by the slider 2 is constant, thereby achieving the effect of quantitative gluing. In addition, after the gluing is completed, the reset mechanism can drive the slider 2 to reset, so that the channel 101 is connected here, and the glue 3 in the channel 101 is replenished.

[0047] As described above, by setting the cylinder 1 and the cut-off mechanism, the slider 2 of the cut-off mechanism is driven to move during the gluing process so that the slider 2 cuts off the glue 3 in the channel 101 of the cylinder 1, so that a certain amount of glue 3 is squeezed by the slider 2 and coated on the connecting piece 10, so that the amount of glue applied each time is kept consistent, avoiding the waste of glue 3, thereby achieving quantitative gluing and improving the coating effect of glue 3.

[0048] Specifically, based on the above overall introduction, the upper end of the channel 101 of this embodiment is connected to the glue 3 supply device outside the gluing mechanism. The glue 3 supply device is a conventional glue supply device well known to those skilled in the art, and can transport glue 3 into the channel 101.

[0049] In addition, the glue 3 of this embodiment is filled in the channel 101. In the process of supplying glue 3 into the channel 101, the glue 3 adheres to the channel 101 and fills the channel 101, so that the glue 3 in the channel 101 always maintains a certain amount. When the cut-off mechanism is not driven, the glue 3 in the channel 101 will not overflow to the outside of the channel 101. In the process of the slider 2 cutting off the glue 3, because the slider 2 itself has a certain volume, the slider 2 can squeeze a certain amount of glue to be coated on the connector 10 when cutting off the glue 3, so that the glue coated on the connector is within the required glue coating amount range, so as to meet the minimum glue coating amount required for the battery pack assembly, thereby achieving the quantitative glue coating effect described in this embodiment.

[0050] In addition, in the specific implementation, the diameter of the lower part of the channel 101 separated by the slider 2 is larger than the diameter of the connector 10 coated with glue, and when the cylinder 1 is buckled on the connector 10, a space of 2-3 mm is left between the slider 2 and the connector 10 to ensure that the glue 3 can cover the connector 10.

[0051] In this embodiment, the slider 2 is connected to the driving mechanism of the glue application mechanism and is driven to move. In order to facilitate driving the slider 2 to move and cut off the glue 3 in the channel 101, the cutting mechanism of this embodiment further includes a push rod 4 arranged along the axial direction of the cylinder body 1. One end of the push rod 4 has an inclined contact surface. When the push rod 4 is driven to move downward, that is, when the push rod 4 is driven by the driving mechanism to move downward and the contact surface is driven to push against the slider 2, the slider 2 approaches and separates the channel 101. Thus, by setting the inclined contact surface, the slider 2 can be pushed to cut off the channel 101, and when the slider 2 is reset, the slider 2 pushes against the contact surface to reset the push rod 4. Specifically, the upper end of the cylinder body 1 of this embodiment is provided with a threaded section, through which it can be connected to a driving mechanism. Through the setting of the push rod 4, the driving mechanism can drive the push rod 4 to drive the slider 2 to block the channel 101, thereby facilitating driving the slider 2 to start the cutting mechanism.

[0052] During specific implementation, as Figure 1 、 Figure 2 and Figure 4 shown, the driving mechanism connecting the cylinder body 1 is arranged in a grip 8. The grip 8 is connected to an external glue 3 supply device through a joint, or the grip 8 is internally provided with a cavity for accommodating the glue 3. And a trigger 801 is provided on the grip 8, and the trigger 801 can trigger a switch inside the grip 8. As an implementation manner, the driving mechanism inside the grip 8 may include a motor and a pushing part driven by the motor and capable of approaching or departing from the cylinder body 1. When the trigger 801 is pulled to trigger the switch, the pushing part can be driven by the motor to push against the push rod 4 to move, so that the slider 2 cuts off the glue 3 in the channel 101, realizing quantitative glue application. As another implementation form, the driving mechanism may include a pneumatic piston connected to an external air source. When the trigger 801 is pulled to trigger the switch, the pneumatic piston can push the push rod 4 to move. Of course, the driving mechanism of this embodiment can adopt conventional mechanisms well-known to those skilled in the art as long as it can drive the push rod 4 to move.

[0053] In addition, the slider 2 of this embodiment is provided with an inclined surface that cooperates with the above-mentioned contact surface, reducing the friction between the slider 2 and the pusher, thereby improving the smoothness of the push rod 4 driving the slider 2 and enhancing the service life of the cutting mechanism.

[0054] To facilitate the setting of the slider 2 and the push rod 4, as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the inner wall of the channel 101 of this embodiment extends radially outward to form an installation groove 102. The slider 2 is slidably and sealingly embedded in the installation groove 102. A chute 103 communicating with the installation groove 102 is provided inside the cylinder body 1, and the push rod 4 is slidably disposed in the chute 103. Through the arrangement of the installation groove 102 and the push rod 4, the push rod 4 is integrated inside the cylinder body 1, thereby improving the structural compactness of the cylinder body 1. In specific implementation, the installation groove 102 can communicate with the outer side surface of the cylinder body 1 to facilitate the installation or maintenance of the slider 2.

[0055] In order to improve the smoothness of the movement of the slider 2 in the installation groove 102, in this embodiment, guide ribs 5 are provided in the installation groove 102, and the guide ribs 5 can be embedded in the grooves on the slider 2. The guide ribs 5 not only play a guiding role, but also can provide additional support for the slider 2 by setting the guide ribs 5.

[0056] It can be understood that compared with the slider 2 being arranged in the installation groove 102, after the slider 2 moves in the installation groove 102 for a long time, the clearance between the slider 2 and the installation groove 102, especially between the top of the slider 2 and the installation groove 102, is likely to increase, resulting in a decrease in the smoothness of the movement of the slider 2, and at the same time, the sealing performance between the slider 2 and the installation groove 102 is decreased, which is likely to cause leakage of the glue 3. After the guide ribs 5 are provided, the guide ribs 5 abut against the grooves on the slider 2, and can provide additional support for the slider 2 to reduce the generation of the clearance between the slider 2 and the installation groove 102, thereby improving the smoothness of the movement of the slider 2.

[0057] Specifically, in order to improve the supporting effect of the guide ribs 5 on the slider 2, there are two guide ribs 5 provided on two opposite sides of the inner wall of the installation groove 102 in this embodiment. Specifically, from the extending direction of the installation groove 102, the two guide ribs 5 are arranged on two opposite sides on the left and right sides of the installation groove 102, so that the two guide ribs 5 can support both sides of the slider 2 in the vertical direction, thereby improving the supporting effect of the guide ribs 5 on the slider 2, and further improving the smoothness of the movement of the slider 2 to a certain extent.

[0058] In order to improve the structural compactness of the glue application mechanism of this embodiment, the reset mechanism of this embodiment is arranged between the slider 2 and the installation groove 102, and the reset mechanism can drive the slider 2 away from the channel 101 to conduct the channel 101. By arranging the reset mechanism between the slider 2 and the installation groove 102, the structural compactness of the glue application mechanism is improved.

[0059] To improve the reliability of the reset mechanism, the reset mechanism of this embodiment includes an elastic member 6, and the elastic member 6 abuts between the slider 2 and the blocking portion 104 on the inner wall of the installation groove 102. When the slider 2 is driven to approach the channel 101, the elastic member 6 is compressed to store energy. When the push rod 4 no longer actively pushes against the slider 2, the elastic member 6 releases energy to push the slider 2 and reset the slider 2 and the push rod 4. Using the elastic member 6 as the reset mechanism has good durability and a large thrust when the elastic member 6 releases energy to ensure the effective reset of the slider 2, thereby improving the reliability of the reset mechanism.

[0060] Specifically, the elastic member 6 of this embodiment is a spring. Compared with other elastic members 6, the spring has a smaller volume and a larger compression stroke, which can ensure that when the slider 2 is reset, the spring can push the slider 2 to move a sufficient distance to re-open the channel 101. At the same time, the spring has a wide range of elastic forces and is easy to adjust, and the elastic force of the spring can be selected according to actual needs to ensure the normal operation of the reset mechanism.

[0061] In this embodiment, the channel 101 is separated due to the movement of the slider 2, and the slider 2 needs to move a relatively long distance towards the channel 101 to completely separate the glue 3 in the channel 101. To shorten the movement stroke of the slider 2, which is beneficial for the truncation mechanism to truncate the glue 3 in the channel 101 and thus realize the glue application action, the truncation mechanism of this embodiment is configured to be two disposed on two opposite sides of the channel 101, and the two truncation mechanisms are arranged oppositely, and the two sliders 2 can approach and abut against each other to truncate the channel 101. By providing two oppositely arranged truncation structures, the sliders 2 of the two truncation structures move together to truncate the glue 3 in the channel 101, thereby reducing the movement stroke of each slider 2 and facilitating the realization of the glue application operation of this glue application mechanism.

[0062] It can be understood that during the process of coating the connecting member 10 by the glue coating mechanism of this embodiment, the lower end surface of the cylinder body 1 is abutted against the end surface of the battery pack housing 9 on which the connecting member 10 is installed. In order to make the glue 3 evenly cover the connecting member 10 and thus improve the glue coating effect, a sealing ring 7 surrounding the channel 101 is provided on the lower end surface of the cylinder body 1 of this embodiment. When the lower end surface of the cylinder body 1 abuts against the battery pack housing 9, the sealing ring 7 can be sealed between the cylinder body 1 and the battery pack housing 9. During the glue coating process, the slider 2 cuts off the glue 3 in the channel 101 and applies a certain pressure to the glue 3. At this time, the lower part of the channel 101, the cylinder body 1, the sealing ring 7 and the battery pack housing 9 enclose a glue coating space, and the glue 3 in the glue coating space can be evenly coated on the connecting member 10. This prevents and avoids the glue 3 from overflowing to the outside of the cylinder body 1 due to the poor sealing performance between the cylinder body 1 and the battery pack housing 9, resulting in insufficient glue coating amount or uneven glue coating on the connecting member 10, and thus reducing the glue coating effect. Therefore, by setting the sealing ring 7, the sealing performance between the cylinder body 1 and the battery pack housing 9 is improved, and further the glue coating effect on the connecting member 10 is enhanced, thereby improving the sealing performance of the battery pack.

[0063] In summary, for the glue coating mechanism of this embodiment, by setting the cylinder body 1 and the cutting-off mechanism, during the glue coating process, the slider 2 of the cutting-off mechanism is driven to move, so that the slider 2 cuts off the glue 3 in the channel 101 of the cylinder body 1, enabling a certain amount of glue 3 to be extruded by the slider 2 and coated on the connecting member 10, keeping the glue coating amount consistent for each glue coating, avoiding waste of the glue 3, thereby realizing quantitative glue coating and improving the glue coating effect of the glue 3.

[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
